Description

This function is identical to split() except that this
ignores case distinction when matching alphabetic characters.

Warning

This function has been
DEPRECATED as of PHP 5.3.0. Relying on this feature is
highly discouraged.

Parameters

pattern

Case insensitive regular expression.

If you want to split on any of the characters which are considered
special by regular expressions, you'll need to escape them first. If
you think spliti() (or any other regex function, for
that matter) is doing something weird, please read the file
regex.7, included in the
regex/ subdirectory of the PHP distribution. It's
in manpage format, so you'll want to do something along the lines of
man /usr/local/src/regex/regex.7 in order to read it.

string

The input string.

limit

If limit is set, the returned array will
contain a maximum of limit elements with the
last element containing the whole rest of
string.

Return Values

Returns an array of strings, each of which is a substring of
string formed by splitting it on boundaries formed
by the case insensitive regular expression pattern.

If there are n occurrences of
pattern, the returned array will contain
n+1 items. For example, if
there is no occurrence of pattern, an array with
only one element will be returned. Of course, this is also true if
string is empty. If an error occurs,
spliti() returns FALSE.

When using special characters such as the tab placeholder "\t" in the split function, be careful not to escape the slash by adding a slah in front of it. To signify a tab, new line or carriage return use only one slash in front of the character. For example:
